TIP-APPLYING mag Application med April 15, 1925. Serial no. 123,25;

The present invention relates to tip applying machines and more particularly to machines for applying tips to the end surfaces of the fabric materials such as belts of d the type disclosed in the patent of Martin,

No. 1,612,978, dated January 4, 1927.

The object of the present invention is to provide a machine for quickly and economically attaching a strip of material to the end facefof a piece of fabric, and more particularly for. applying a tip to the type of belt described in the patent above referred to. i

With this object in view, the present invention cons'istsin certain novel features of construction, combinations and arrangements of parts hereinafter described and particularly defined in the claims.

In the accompanyingdrawings illustrat- 2 ing the preferred form of the inventiomFig.

The above mentioned patent discloses a .0 beltconsistingof an elastic webbing having [a covering of leather si irrounding its sides and edges and provided with a strip of leathercemented to the pointed end face of the belt to give a finished appearance to the hel t and also to protect the side covering from haying or loosening upon passing of the endfof the belt through the" buckle; In

order provide for the automatic attachment of such a tip' to the end face of the belt, the illustrated embodiment the present inyention comprises in general three Fig. 6 is a sectionaldetail mechanisms,a belt gripping mechanism for liolchng the end portion of the belt, a tip attaching mechanism serving to engage the end face of the belt presented by the gripping mechanism and press a ti .of leather tape firmly thereon, and a tape eedmg mechanism operating automati a ly, predetermined intervals to draw a strip of tape acrossthe machine in position to be engaged by the tip attaching mechanism and to be pressed upon the belt. In the illustrated embodiment ofth invention, the belt gripping and tip attaching mechanisms are mounted forrecipjrocating motion toward and from eachot'her, being separated during a portion of the cycle of operations to permit the insertion of a new belt to be tipped and the operation of the feeding mechanism to draw a strip of tape between them, and

thereafter approaching each other for engagement of the tip attaching devices with the end face of the belt. The three mecha nisms are operated in timed relation by means of suitable ,cams. The gripping and tip attaching mechanisms are cooperatively arranged so that upon their approach they actyto press the tip upon the end face of the'belt and also to sever the tape immediately adjacent to the side edges of. the belt and :flush therewith, thus insuring that the end of the belt is properly covered to give a good appearance and to protect the edges of the leather side covering.

Referring to the drawings, the machine comprises a frame 10 upon which are mounted for reciprocating motion a gripper slide 12 and a tip attaching slidele The slide 12 carries a belt gripper constituting the grip ing. or holding mechanism and indicate generally at 16, and the slide 14 carries the tipfiattaching mechanism indicated generally at 1.8. The slides 12 and 14 are recip'r'ocated :to bring the gripper 16 and the ti attaching devices 18 toward each other'ldy means of cams 19 and 20, the former cooperating with the gripper slide through a cam'roll 21 .in the cam groove 22,

and the latter servingto actuate the tip attaching slide by means of a cam roll 23 in the groove 24:. The studs 25 and 26 conjnectinglthe rolls with their respective slides pass through suitable openings in the frame.

The cams are mounted on a cam shaft 27 members 36 adjustably secured to the slide 12. The blocks are formed with grooves 37, as shown in Fig. l0, rounded to conform to the shape of the sides of the belt and separated a distance equal. to the width of the in order that the belt may be accurately -positioned' for presentation to the tip applying devices. Each block is formed with an inclined groove 38 in its upper face, which serves as-a' guide for the tape. Secured to the slide 12 is a plate 39 upon which is attached a box-shaped belt guide 40 serving to receive the belt and guide it to the blocks The belt is retained within the gripper by means of a gripper plate 42 which is spring-pressed toward the belt by means of a spring received in a spring cup 4M3, which in turn is received in openings in the slide 12 and the plate 39. The spring cup 46 cooperates with a cam plate 48 on the frame having a cam surface which is adapted to force the gripper plate against the belt with increased pressure as the slide is moved up. The gripper is retained in position by a ledge 49 formed thereon and overlying the box 10, and a pair of lugs 50 struck up from the bottom of the plate and received in suitable openings in the be 40. The belt, which is indicated at 54- in Fig. 3, is inserted in the gripper when the slide 12 is at the bottom of its stroke, the spring pressure being at this time sufficiently small to permit ready insertion of the belt, while upon the start of the upward movement of the slide the spring pressure is increased to prevent accidental displacement of the belt. The belt is accurately positioned in the gripper by means of a positioning dog 56 having a tail 58 against which a corner of the gripper abuts when the latter is at the bottom of its stroke. The dog has an upward projection (30 bearing against the edge of one of the blocks 35, and the surface of the projection is such as to determine the proper position of the belt within the gripper, as shown in Fig. 3. Upon upward movement of the gripper slide the dog 56 is thrown in a counter-cloclnvise direction so as not to interfere with the motion of the slide, and upon the return movement the engagement of the gripper with the tail returns the dog to its original position. I

The tip attaching mechanism 18 consists of a presser 62 adjustably attached. by screws 63 to the slide let in a position directly above and in the plane of the belt. The presser has at its lower end inclined surfaces 64 conforming to the pointed end of the belt to adapt it to engage accurately with the pointed end of the belt'to press the tip thereon as the gripper and presser are moved toward each other. The presser is of such size and shape as to be received in the grooves 37 of the belt holding blocks after the tip has been pressed upon the end of the belt, the sides of the presser being rounded, as indi% rated at 5 in Fig. 9, to conform to the shape of the grooves to form shear surfaces between which the tape is cut adjacent the edges of the belt. Goopcrating with the prcsser are two belt guides indicated generally at 66 and 68 for stiffening the belt and maintaining it against sidewise flexure while the tip is being applied, the former constituting a tip guide adapted to engage with the central portion of the end of the belt,

and the latter constitutingan edge guide to.

engage with the edge portions of the belt. The tip guide 66 is only of sufficient width to engage the central portion of the belt and comprises a back plate 70 slidingly received in a recess 72 in the slide it and connected by a lug 74: with a short front plate 76. he lug 74 lies in the plane of the presser and the plates 70 and 76 are adapted to embrace the tip end of the belt, the lower ends of the-plates being beveled, as shown in Fig. 2, to insure engagement of the belt between the plates as the slides are brought toward each other. The lug 74 has a triangular notch 78 in its lower end to position the pointed end of the belt. The guide 66 is yieldingly mounted on the slide by means of a pin 80 secured to the back plate 70 and extending through a slot in the slide 14: to be pressed downwardly by a. spring 82 received in an openingin the slide. The guide thus has provision for movement relative to the presser, the latter having a recess 84: to accommodate the lug 74; when the guide is moved. The edge guide 68 which serves also as a-guide for the iower end of the presser consists of a plate having depending side portions 86 engaging the front surface of the presser and terminating flush with the lower pointed ends of the presscr, the portions 86 being formed with blocks 88 similar in form to the belt holding blocks 35 and embracing and conforming to the sides of the presser as shown in Fig. 9. The blocks 88 are provided with tape guiding grooves 90 in their under surfaces. The guide 68 is mounted for free sliding movement with respect to slide 14, for which purpose it has a reduced portion 92 received between the screws 63, and its upper end is provi'ded with a slot 94 within which is received the shank of screw 96 secured to the slide 14:.

" neaegooo 'lhe operationp of "the above mentioned parts is descnibe'd as follows: l'nwthe tion-shown infFigs. land 2, a ti operation has just been completed, the slides having been returned to their 1 original positions. At this time the cams 19 and 20 have arrivedntu dwell portion with relation to placed within the gripper, its ointed face engaging with the positioning cog 56. The

end face of thebelt is preferably provided with a. coating of cement; also during this dwell period a strip of tape 'cementedon one side is drawn across the machine between the gripper and the tip attaching devices directly above and in "alignment with the end face of the belt bymeans of automatic devices presently to be described in detail.

After this 180 dwell rotation, the actuatingportions A and B of the cam grooves 22 and 24:, respectively arrive at a position to raise the slide 12 and depressthe slide 14 through their corresponding cam rolls. "As will be apparent fremFi-g.' 2, the aetiiatin g portion B of the cam gi'bove 24 serves to complete the movement of the slide 14 Within a relatively few degrees-of rotation of the cam shaft, While the portion A oftheeam groove 22 acts through a rotation of ap- 1'n'oximately90" to efiectthe complete movement of the gripper slide. The movement of the slidehl is such as to bring the belt end guide 66 into a position to embrace the tape the gripper slide having been moved during this period sufficiently so that the end of the belt is received between the plates 70 and 76 of the guide. The guide 68 comes to aposition such that its lower end is slightly above theiline of the tape. Gontinued upward motion of the slide 12 eauses the tape to be engaged between the pointed end of the belt andthe lug 7 1, and-the guide 66 pushed upivard ly against the spring 82, the lug being received in the recess 84 of the presser. The posit-ion ofithe parts at tape running over the endsiotlthe resser. Fun [her lll'iWtUtl-l110tl0n out the gripper slide brings the tape into engagement with the parser, that owing to the conformitypt the presser to the shape of the heltendjthe tape is firmly pressed upon the end face of the belt. During thistimo the side edges of the belt are engaged by the lower portions of the guide 68. The cams 19 and are so arranged that at the limitof the upward movement of the gripper slide the belt Will have been depressed through the gripper by the action of the presser thereon, as

shown in Fig 8. "The edges of the presser extend into the guide blocks of the gripper, and because otfthe conformity of 311831785881 to the shape ofthe grooves 3? the t the side edges of the belt, the presser haw ingbeen etl'ective during thisentire operz ape is severed immediately adjacent to tion to force the tape firmly upon the end of i the belt. It will bei seen that the belt edge a guide 68 serves also as a guide for the presser, pnesentin the lower end thereof accurately for a mission into the guide blocks 35 of the gripper. Prior to the entrance of the presscr into the guideblocks 35, the latter engage the lower ends of the under side Wound upon a drum 104C and leads through a pair of te-nsloning rolls 106 and a pair of tape present ngrolls 108 in position to be engaged by a pair of feeding fingers to be drawn across the front of the machine. As shown in Fig. 6, the rolls 106 V areot a form to engage and guide the-tape,

the upper roll being formed with a gnome within which the tape is positioned by the periphery of the lower roll. The upper roll pivoted on. a bracket 110 attached to the frame oi the machine, and the lower roll is mounted for rotation on an arm 111 having a hub 112 loosely mounted on a stud 113 journaled in a boss 114i ofithe frame, the/lower roll being urged toward the upper roll by means of a counterweight lltt con- 'neeted with the hub 112. The tape presenting rolls 108 are of the same form as the rolls 106 and are mounted on arms 118 and 120, the former being secured to the stud 112, the latter to a similar stud 122 journaled in the boss 11 1. The arms 118 and 126) are operatively connected together through gears 124 and 126 on the studs 113 and 122 respectively the arms being m; 2d together in a position to cause the rolls 108 to grip the tape by means of a tension spring 1.28 taking between the upper arm 120 and a fixed part of the machine. The tape as presented by the rolls 106 and 108 is adapt ed to be engaged by a pair of feeding rolls 130 ofsimilar form to the above menti tied rolls and mounted upon feeding finge and 13 1. The fingers are pivoted at 136 and 138 respectively upon a cross slide MO, which is mounted for reciprocatory move--- mentin Ways 142 of the machine fiecu l to the studs l36'and 138 are gears Mat. a ll 146 which operatively connect. the feeding normally being urged toward closed position by a tension spring 148 connected between them. The slide 140 is reciprocated to move the feeding fingers back and forth across the front ofitlie machine by means of a lever 150 having a forked end engaging a pin 152 on the slide, the arm 150 be ing connected through a rock shaft 154 and an arm 156 to a cam roll 158 received in the cam groove 22 of the cam 19 at a point diametrically opposite from the gripper slide actuating roll 21, so that the feeding fingers are reciprocated when the gripper slide is stationary, and vice versa. The feeding rolls 130 are adapted to engage the tape at a point between the rolls 106 and 108, as shown in Fig. 4, and for this purpose it isnecessary to separate the rolls 130 to clear the rolls 108 upon a left-hand movement of the cross slide 140 and to separate the rolls 108 to permit the rolls 130 to pass therethrough upon a right-hand movement of the slide. It will be observed from Fig. 10 that the rolls 108 project forwardly from their arms 118 and 120, while the rolls 130 are mounted on the rear side of their re-. spective feeding fingers, so that there is no interference between the arms and the feeding fingers during the feeding operation. In. order to provide for the opening and closing of the feeding fingers, a vertical reciprocating slide 160 is mounted on the machine frame between the blocks 32 and a pair of blocks 162. lhe slide has a bracket 164 (Fig. 2) carrying a cam roll 166 received within the groove 168 of a cam 170 mounted on the cam shaft 26 between the cams 19 and 20. At its lower end the slide 160 is provided with a groove 171 to receive a tongue 172 of a bracket 174 upon which are mounted a pair of studs 175 carrying linger separating rollers 176 engaging opposite sides of the lower feeding finger 134. The upper surface of-the bracket 174 is adapted under certain conditions to abut against a shoulder 178 formed on the slide at the upper end of the groove 171. Re ceived in a similar groove 180 of the slide is a tongue 182 of a bracket 184, which at its lower end has a lug 186 adapted to enthe lower surface of the bracket 174. The bracket 184 is urged upwardly by a heavy coil spring 188 connected between screws 100 and 192 attached to the slide 160 and the bracket- 184 respectively. Referring to Fig. 2, the arrangement is such that when the cross slide 140 is completing its left-hand movement through the actuation of the cam roll 158 by the portion A of the groove 20 the cam roll 166 engages a portion C of the groove 168 to depress the slide 160, this action, of course, taking place while the slides 12 and 14 are separated. Upon depression of the slide 160, engagement of the shoulder 17 8 with the bracket lingers, the cam groove 168 arrives at a steep v portion D with relation to its cam roll to retract the slide 160 in order that the rolls 130 mayclose upon the tape through the action of the tension spring 148. The steep portion of the cam groove is extended to a point indicated at E to retract the slide 160 slightly above its original position to place a tension on the heavy spring 188 in order that the projection 186 may be forced against the bracket 174 with a yielding pres sure to close the rolls 180 firmly upon the tape While the slide 140 is being moved in a right-hand direction to draw the tape across the machine. At the limit of the right-hand movement of the feeding fingers the additional pressure brought to bear by the spring 188 is relieved by a declining portion F of the cam groove which moves the slide 160 downward to its originalposltion. Upon the right-hand movement of the feeding fingers, rotation of'the rolls 130 is prevented by means of a ratchet wheel 204 secured for rotationwith the lower roll and engaging with a pawl 206 pivoted on the lower feeding arm and urgedtoward the ratchet by a torsion spring 207. At the limit of the feeding movement, the pawl is removed from engagement with the ratchet through the engagement of the tail 208 of the pawl with the stud 175 upon which the upper separating roller 176 is mounted. In

order to provide for the separation of thetape-presenting rolls 108 upon the feeding movement of the feeding fingers, a cam follower arm 210 is secured upon the inner end of the stud 122 and carries a cam roll 212 adapted to engage with a cam 214 secured on the periphery of the bevel gear 28. Immediately after the closing of the rolls 130 upon the tape, the cam 214 lifts the arm 210 so that the rolls'108 are separated through the connection of their respective arms through the gears 124 and 126. After the feeding fingers have been moved suffi- V ciently to the right to clear the rolls 108, as

illustrated in Fig. 5, the latter are again closed on the tape by the action of the tension spring 128, which is assisted in its closing movement by a cam 216 secured to the under surface of the cam 20 and adapted to engage the roll 212. It will be seen that prior to the feeding movement, the tape is positively held between the rolls 106 and 108 for presentation to the feeding fingers, and furthermore that the tape is always engaged either by the rolls 108 or the rolls 130. Moreover, immediately after the start of the feeding movement of the rolls 180 the rolls 108 close on the tape to position the additionalpressuredue tout-he splring 188.
